  • Rotary coupling apparatus using composite materials
    Patent number: 5540621
    Abstract: To couple a driving shaft of a machine to a driven shaft, a coupling assembly is mounted to the driving and driven shafts and includes a flexible coupling element. The flexible coupling element includes a plurality of first fasteners adapted to be connected to the driving shaft and a plurality of second fasteners adapted to be connected to the driven shaft. A plurality of fibers connects different ones of the first fasteners to different ones of the second fasteners so that the first fasteners applies force to the second fasteners to transmit torque. The filaments or fibers are looped around the fasteners and the coupling element has a thickness in the range of 1 percent to 10 percent of its diameter.
